Swollen gum at end of teeth
A swollen gum at the back of the teeth may reflect plaque, an erupting molar, trauma, or infection that needs examination.
The short answer
A swollen gum at the back of the teeth may come from trapped plaque, an erupting tooth, trauma, or infection around a tooth.
What is the direct answer?
What does this question mean?
The swelling may be gum behind a molar, tissue over a partly erupted wisdom tooth, or an abscess beside a tooth. Examination distinguishes these causes.
What can you do next?
Rinse gently, brush carefully, and use an appropriate interdental cleaner without forcing it into the swelling. Do not puncture or squeeze the lump.
When should you seek dental care?
Get prompt care for spreading swelling, fever, pus, severe pain, difficulty swallowing, facial swelling, or limited mouth opening.
What should you ask the dentist?
Ask whether the swelling is over an erupting tooth, beside an infected tooth, or caused by gum disease, and whether imaging is needed.
Frequently asked questions
What is the main thing to check?
The clinician should identify the tissue, tooth, appliance, or product involved before recommending treatment.
When should I arrange an appointment?
Arrange one for persistent, worsening, or unexplained symptoms, and seek urgent help for breathing or swallowing difficulty.
